HELP: ED Falcon Brakes - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

I have a 7/94 ED Falcon Gli Sedan, 4.0 litre auto, air,
steer, and ABS.

Apart from the shitty brake fade (standard), the
problem starts here: I replaced my battery 2 months
ago (Apollo, Oz made, 2 years warranty). When I put
the battery in and bolted it back up, I started the
car, and there it was, the ABS light on constantly in
bright red, saying "CHECK ABS". So I did.

My uni teacher told me to disconnect the ABS from the
actual main supply unit, which sits under the front
left gaurd, under a plastic cover. I did this, twice,
once with the ignition on and once with it off= NO GO,
still have red light.

He also told me to disconnect each ABS sensor (the
ones that sit behind the disc, on the stub axle, held on by a small 10mm
bolt) and clean them with kerosene or degreaser. They
were really dirty, greasy, and covered in brake
filings/dust.

I cleaned them, bolted them back up and still the light was there.

Checked all fuses, all OK.

Checked all wiring going to battery, all OK.

But the damn light is still on. I know for fact that
the actual ABS is not working, cos I know the feel and
difference know on this car between ABS and non ABS.

What do you think the problem is?

Any ideas anyone, please reply via posting a reply, email, or mobile.

Im not sure if this applies to your prob but anyways... Ford found my prob was that the actual wiring connector/s had gotten abit of moisture inside it & had a lite coat of corrosion on it which inturn gave me the warning lamp status..
dont get me wrong mate but why bother messing with it just pay ford for a diagnosis $40 too easy & then fix it yaself..
P.S. those sensors are freak'n expensive man... did you also clean the tone wheel that the sensor gets its input from??

Thanks "svo302" for your reply.

And yes, I took the actual discs off and cleaned the so called "tone wheels" as you call it.

On the rear, I think they (the tone wheel) are actually part of the axle, but they were fairly clean.

The front "tone wheels" are on the actual discs, like a round ring pressed onto the inner disc hub. They were dirty, covered in grease and brake dust. Cleaned them to, but that fu;;ing light still shines red brightly...

Could possibillity be the abs pump/module itself...... hope you find the prob mate..
Cheers

i had this prob with my car about 2 months ago. they put it on the diagnostics tester and found it was a diode fault. and i had to have the abs module which sits under the dash near the steering column replaced

Make yourself a codereader with a LED and a resistor and read the ABS codes (or use a multimeter) see: http://www.autoemf.com.au/ford_eec5.htm,
http://www.autoemf.com.au/eec4test.htm and http://www.corral.net/20anngt/images/test.gif the ABS codes are read in the same way as the engine codes but connect to the ABS connectors instead. With the ignition key set to run the first ABS code read should be 90 (the model number) the codes you may get then are:

10 Seperator code
11 system pass
17 Solenoid always on
18 ECU failure
29 Modulator \31 ABS Warning light \32 Solenoid Voltage low
33 Warning Light Diode failure
34 Excess decay35
35 pump Motor Cirecuit
36 Extended brake Deacy
43 RHR Sensor
44 LHR Sensor
45 RHF Sensor
46 LHF Sensor
47 Wheel Speed
71 RHR Sensor Continuity
72 LHR Continuity
73 RHF continuity
74 LHF Continuity
90 Model ID

These codes get more explanation in the manual so if you get a code post again and I will provide more details of likely causes.

For EL - EF owners wanting ABS codes see http://www4.tpgi.com.au/users/mij/Au.../ABSCodes.html

either the wiring from abs module to computer, or as EDXR6 said, the main module is up to be replaced.
